305-022-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-022-556-203 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It accommodates board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester insulator provides thermal stability

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical connection
• Industrial control systems utilizing dual-edge circuit boards
• Communication equipment interfaces needing robust signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB thickness limits before procurement. Cross-reference RoHS compliance status with current manufacturer declarations to meet regulatory requirements for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, panel-mount interface is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch suits high-current applications where spacing reduces crosstalk. Verify that the vertical mounting style aligns with chassis constraints and that the green insulator color meets visual identification standards.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles, primarily focusing on panel-mount headers and receptacles. The 305 series is characterized by its durable construction and suitability for harsh industrial environments requiring stable electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-020-556-202 and 305-022-556-202. Verify that alternative part numbers match the 22-position requirement and dual-edge female configuration. Confirm identical pitch and board thickness tolerances to maintain mechanical fit.
